Abstract: The method of making a die set line involves correction of the first blanking die set in the line, in accordance with the results of stamping the blank produced using the other die sets. The blank is made with a wire tool electrode by virtue of electrical discharge machining. The electrical discharge machining program is adjusted in accordance with the results of stamping the blank using the other die sets in the line. Thereafter, once the corrected blank is produced, it is used for making tool electrodes for electrical discharge machining of the working parts of the first blanking die set in the line.

Abstract: The method of making blanking die sets provides for preparing a stack of blanks of a predetermined profile for use as positive tool electrodes. The working parts of blanking die sets are subjected to prior machining. Production holes are provided in positive tool electrodes, after which using one of the positive tool electrodes, the working parts of the die set are marked off, dimensions of the working profile of the tool electrode are reduced either mechanically or chemically, and the female die and the stripper are subjected to rough electrical discharge machining. The second positive tool electrode is used for finish electrical discharge machining of the female die and the stripper. The third positive tool electrode is used for burning through a stack of negative tool electrodes wherein production holes are provided. The negative tool electrodes are used for rough and finish machining of the male die and the knock-out.
